What exactly is a Tower Garden and how does it differ from traditional gardening?
A Tower Garden is a vertical, aeroponic growing system that allows you to grow plants without soil. It utilizes a nutrient-rich water solution that is pumped to the top of the tower and then trickles down over the roots of the plants, providing them with the water and nutrients they need to thrive. This innovative system saves space, reduces water usage, and minimizes the need for weeding and pest control compared to traditional gardening methods.
Unlike traditional gardening where plants are rooted in soil and nutrients are absorbed from the ground, Tower Gardens suspend plant roots in air or a soilless medium. This method promotes faster growth, higher yields, and healthier plants because the roots have direct access to oxygen and nutrients. The closed-loop system also recycles water, making it a more sustainable and efficient option for growing fruits, vegetables, and herbs.
